If you plan to have multiple plurals inside your code, using a function such as may_pluralize() increases readability. To use the function, pass may_pluralize() the singularform of the word as the first argument and the amount as the second.Inside the function, there’s a large array, $plurals, that holds all the special cases. If the $amount is 1, youreturn the original word. If it’s greater, you return the special pluralized word, if it exists. As a default, just add an s to the end of the word. As written, may_pluralize() encapsulates pluralization rules for American English.Obviously, the rules are different for other languages. If your application only needs toproduce output in one language, then a function like may_pluralize() with language specific logic is reasonable. If your application needs to produce output in many languages, then a more comprehensive approach is necessary.
